ERASTUS J. MULKEY, OF AMERICU S, GEORGIA, ASSIGNOR OF ONE-HALF TO ALLEN FORT, OF SAME PLACE. i

WELL-AUG'ER.

SPECIFICATION forming part of Letters Patent No. 267,918, dated November 21, 1882,

Application filed June 1'7, 1882. (No model.)

To all whom it may concern:

Be it known that I, ERASTUS J. MULKEY, of Americas, in the county of Sumter and State of Georgia, have invented certain new and useful Improvements in Well -Augers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the To same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved well-auger. Fig. 2 is a longitudinal 1 sectional view of the same. Fig. 3 is a perspective view of the bottom part with its adjustable bits and dirt-gates. Fig. 4 is a longitudinal sectional View taken at right angles to .the view shown in Fig. 2, and Fig. 5 is a sectional detail view of the mechanism for adjusting the pitch or angle of the adjustable cutting-bits. 7

Similar letters of reference indicate corresponding parts in all the figures.

2 5 My invention has relation to well-angers; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed, whereby the anger may be adjusted according to the nature of the ground in which it is to be used.

In the accompanying drawings, the letter B indicates the auger stem or shank, which is forked at its lower end, as shown at bl), for

3 5 the attachment of the bottom plates, 0 0. Upon the upper part of the shank, a suitable distance above the barrel G, is fastened a head or block, A, by means of curved arms a a, forming loops which project laterally from the stem, to the top of which is attacheda suitable coupling, B. The barrel G is made in two semi-cylindrical parts or sections, which are attached to the central stem,.B, by means of arms H H at top and angle-pieces h h at hottom, connecting them with the rigid semicircular plates 0 G, which have recesses K in onehalf'ot' their inner edges, as shown in Fig. 3, beneath which are placed the removable dirtgates E E, which are fastened to the plates 0 G by screws or nutted bolts 6 e. V

D D are the, bits or cutting-blades, one or both of which are madeadjustablebymeans of a set-screw, 0, working through the bottom plate, '0, and bearing with its lower or outer end against a lip or projection, d, of the bit, which is bolted to plate 0 by bolts 0 c in such a manner as to permit the bit to rock upon its bearing-plate O.

The dirt-gates E are arranged between the recessed plates 0 and auxiliary bottom plates, G, which are interposed between the bits D and plates 0, so as to partially close the openings or apertures between the bits and the dirt-gates.

From the foregoing description, taken in connection with the drawings, the operation of 'my improvedwell-auger may be readily understood.

The circular head or disk A above the barrel serves the twofold purpose of a guide for the auger-shaft, preventing the auger from working crooked while boring, and forming a hood or shield, preventing debris from falling into the barrel.

If desired, each piece of shafting may be provided with one of these circular disks, serving as a guide to cause the shafting towork straight in the center of the bore, and if the sh afting should break, the auger may readily be drawn out by means of ropes or chains having hooks or grapples at their lower ends, which may be hooked into thearms a of the auger stem B.

The auxiliary dirtgates E and auxiliary bottom plates, 0, are only brought into play when the anger is used for boring either in very soft or in very dry earth, which will not readily stay within the auger. For ordinary work they are not used, and may be left off altogether.

Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States- 1. In a well-auger, the combination, with the barrel G and its central stem, B, of the 9 5 fixed disk A and arms a a, bent to form laterally-projecting loops connecting the disk with the stem, substantially as shown and set forth.

2. In a well-auger, the combination, with the barrel G and its fixed bottom plates, 0, In testimony that I claim theforegoing as of the removable dirt-gates E, bits D, having' my own I have hereunto aifixed my signature lips d, bearing against set-screws 0, working in presence of two witnesses. through the fixed bottom plates, and auxiliary ERASTUS J MULKEY. plates 0, interposed between bits D and dirt- Witnesses:
